Despite having higher claim frequencies than prime age drivers, the increasing number of older drivers is not expected to affect overall collision claim frequency. The increase in the proportion of older drivers is expected to be offset by a decrease in the proportion of the youngest drivers. While the decrease in the proportion of younger drivers is not as big as the increase in older drivers, their claim frequency is much greater than that of older drivers.
